  1. 32. Beyond Intensity: Linear Polarization as a Proxy for Solar Vortices1

    Science Meeting
    Invited

    Vortex motions in the solar atmosphere play a crucial role in energy transport and plasma heating. Current observational methods for detecting vortices rely primarily on intensity morphology, which is limited in sensitivity and often fails to capture the full vortex population. In this Letter, we propose linear polarization (LP) as a novel diagnostic for identifying vortices in...

  2. 22. Observational Evidence of Directed Information Transfer by Solar Vortices
    Suzana de Souza e Almeida Silva (University of Sheffield)

    Science Meeting

    We analyse high-resolution data from the TuMag instrument aboard the Sunrise III balloon mission. Vortices are identified using a velocity-independent approach that detects their signatures directly in intensity patterns, combining morphological identification of vortex structures with Spectral Proper Orthogonal Decomposition to extract coherent dynamical patterns imprinted by vortices in Mg...

  3. 13. SCIP multi-line inversions in the 850 nm window: height stratification of solar magnetic fields in a pore

    Science Meeting

    We analyze spectropolarimetric observations acquired with the SCIP instrument in the near-infrared spectral window CH1 around 850 nm. This wavelength range contains a total of 12 spectral lines sampling different layers of the solar atmosphere. In this work, we focus on a subset of seven Fe and Ca lines, spanning photospheric, upper-photospheric, and chromospheric heights, including the Ca II...

  4. 33. Analysis of extremely asymmetric Stokes $V$ profiles in quiet Sun regions with the Sunrise/SCIP instrument
    Shujun CAI (National Astronomical Observatory of Japan)

    Science Meeting

    We investigate small-scale magnetic features in the quiet solar photosphere through high-resolution multi-wavelength spectropolarimetric observations taken by the Sunrise Chromospheric Infrared spectro-Polarimeter on board the Sunrise-III stratospheric balloon-borne solar observatory. The instrument allows for high signal-to-noise observations of multiple spectral lines.
    Our analysis focuses...

  5. 24. 3D magnetic structures triggering an M-class flare observed with SUNRISE III
    Ryohtaroh Ishikawa (National Institute for Fusion Science)

    Science Meeting

    SUNRISE III observed an M5.3-class flare on July 13th. The 3-hour observation began at 11:44 UT, one hour before the GOES X-ray flux peaked at 12:40 UT. SCIP obtained full Stokes profiles in the 770 nm and 850 nm range, covering the photospheric Fe I 849 nm, the upper photospheric K I 766 nm and 770 nm, and the chromospheric Ca II 849 nm and 854 nm lines. The FOV of SCIP covered a part of the...
